I recently had some hunting buddies down from Canada. They were using older Sov's with the 8" coinsearch coils. I was using the GT with the 8" Tornado. When they would find a deep coin signal they would call me over to check it. I would not get a solid signal in anyway just chirps that would not lock on while there machines seemed to grab the signal with little effort. After this happening on about 10 different targets I was getting fed up with the 8" Tornado coil. I bought a 8" coinsearch and I have noticed that it grabs the deep signals quickly and locks on. I am sold on this coil and will not be using the tornado any longer.

8" Coinsearch coil on GT
- Thread starter JohnTN
- Start date
The 8 inch coinsearch coil is a good one thats for sure, just not water poof. I always recommend this coil for those starting with the Sovereign as the signals seem to linger on more giving a better chance of hearing them. The S-8 of Sun ray will go deeper and see targets close to trash better, but harder to use for a beginner I feel. I just got a like new 8 inch Tornado coil to try when the ground thaws and been told it works like the Coinsearch, but this one is water proof. The coil I felt didn't have the depth was the 8 and 10 inch BBS coils, but I know the 10 inch Tornado is very good so felt the 8 inch would be good too.

I own the new tornado 7.5 inch coil, and the sunray,
I have found that the sunray goes deeper when that sensitivity is set in the low numbers, but when you push up the sensitivity, the tornado is just as good.
I really like the new tornado coil.
On a differant note, I have just discovered the sov works very very well when left in tracking mode.
good luck

I have used both the 8 inch Coinsearch coil and Tornado 800.The Coinsearch may edge the Tornado on depth.I found the smaller coil to be smoother and is easier to wiggle for the high tone number lock on for good coins.I remember last summer going to a very high trash park with my two friends one was using a CZ70 and a DFX.that little 800 coil kicked a$$.My two friends wanted to leave because they weren't having any good finds in the trash. I found a 1941 Canadian Quarter a 1950 Roosevelt dime and a lot of wheat's and older Jefferson nickles in about two hours time.Of course the Sovereign is a good unit but the little 800 coil sure separates nice with good depth.

The two tornado coils are excellent. I sold off both of my coinsearch coils because I felt the smaller tornado coil equaled the coinsearch in depth and bettered it in seperation. Plus its waterproof which is always a plus. The one downside, like with any open coil, is they get hung up on roots and such.
Piero your correct, that tracking mode gets down deep doesnt it.....has that wider response too, just like the disc mode but more sensitive.

I dont have the manual out for my GT so I cant reference what your saying here about fixed being deeper. I know mine goes deeper in the two all metal modes(pinpoint and the tracking all metal) than in disc. Ive never mastered the all metal audio as some have said they have so I dont hunt in that mode much, but you can tell if its deeper simply by checking targets and switching from all metal to disc. Be careful in track, you can loose the deepest targets as they will blend into the ground, so make sure not to make to many passes before you dig or you can loose it.
By any chance your not talking about the auto/manual selection on the sensitivity setting? Just want to be clear.

I said the 7.5 coil goes as deep when the sens is turned up.
Not in tracking.
In tracking, I find it is very stable, but then again, it should be.
Also, I am detecting in ploughed farm land, with heavey minerals. this might be differant to your sites.
One thing to look out for, in tracking, is if the tracking over ground balances the detector.

Two years of discussion on this forum regarding depth comparisons between the GT in Disc or A/M has pretty much come down on the Disc side for better depth, and that has been my experience as well. The manual does state a slight increase in depth when using Fixed A/M versus Tracking mode. Of course a related question {disregarding depth) is WHY use A/M anyway - Unless your looking for iron targets don't you want the GT to tell you all it knows??? I don't argue with that,
However, there is an A/M technique that is worth practicing. I often switch from Disc to Fixed A/M to check coin targets. I started doing this after reading CJC.s book on the SOV..Of course using this technique could be influenced by the depth of the target (possibly losing it) but If you switch to A/M fixed after getting a good coin tone and sweep the coil over the target to pick up the A/M resoponse and you get a short low-high-low signal it is almost always a coin and not a piece/clip from a pop-top or other trash pretending to be a coin. I can't expliain the sound by text (and I think CJC had a problem with it too) but if you practice checking coins by doing this reverse disc/AM check I think you will find that it is another tool you can use.
There is one thing about this GT Disc or A/M Depth question that I have never understood. . When switching to A/M Pinpoint from Disc Mode to help locate a target I have NEVER lost it. Pinpoint always gives a reponse. regardless of depth. This tells me that Pinpoint is equal to or better than Disc for depth. The manual does say to not use pinpoint as it somehow effects ground balancing but I have never noticed this. So if you want to get depth using A/M why not try Pinpoint? HH Don

Very good Don!!!!!!!!
You have learned about how to use the tone shift ID in all metal mode. I'm impressed.
You might be one tough guy to hunt behind.

How much difference in depth did you find between the BBS and others?
I've only had the 7.5" BBS and have never gotten the depth that I've seen reported by others. Six-eight inches seems to be max for me on a coin. Haven't been sure if it was me or the machine but I've tried my darnedest to listen for faint threshold changes and have yet to find a coin deeper than that (that I can recall). I bought the machine used and have thought of sending it to Minelab to have them check it over to see if's working right or been messed with.
Anyone have a larger non-BBS coil they want to sell?

We had did some test back when I sold my XS with the 8 inch coin search coil to a friend of mine and I got the new XS2 with the 10 inch BBS coils. The 8 inch Coinsearch seen some deeper coins then my 10 inch BBS coil did not which shocked me. I found a used 8 inch coin search coil and put on my XS2 and noticed right away I was finding deeper coins, but maybe too the 10 inch was masking coins with the trash around. I would say the 8 inch coin search got me a good 2 inches deeper. Now with the 8 inch coin search coil and my XS2 is what I used on the challenge I got to find one old coin another guy missed with his Garrett and I found over 70 old coins he had missed. Some of these were 12 inches deep or more, but they didn't sound as good or read as good as a coin at 6 inches. Also I had to go super slow to hear these tone changes and work them.
Over the years I have bought a few Sovereign and some had the 8 inch BBS coils and they did OK, but never found any real deep coins (coins over 8 inches) Now the Sun Ray S-8 I found the signals were not as notice able like the coin search coil, but seem to get coins in trashy area better and some that were very deep too, but you have to listen closer with this coil over the 8 inch coin search coil. Now with the 10 inch Tornado coil on my GT I was going to put on my coin search coil, but after using it for a while I find it does very well for me and now just picked up a 8 inch Tornado coil to try and see if it is as good as the 10 inch or even the 8 inch coin search coil.
